The purpose of this study is to investigate the value PH on the seed germination of corn seeds. The soil through the process of the experiment planted corn, including loam soil incorporation of clay rice stubble, soil manure, soil fertilizer.Loam, clay soil of rice straw incorporation, soil, manure and soil fertilizer, it can be concluded that the soil with PH optimum planting corn most. Including clay rice stubble measuring value PH has 6.5 and soil manure measure PH has 6.3 then experimented planting corn into the soil, soil clay rice straw incorporation, soil, manure, soil fertilizer, the period 4 week. And record the length of the germination of corn were analyzed and compared.Corn grown in terracotta rice stubble grow much measure the height 35 cm later measured value PH. After experiment again found suitable land to grow corn, including pottery, stubble rice, measure the PH has 6.5 and soil manure measure PH has 6.0 and bring the PH before the experiment and the PH. After the comparison, it can be concluded that the soil suitable for planting of grain at สุดและ make rice grow most is clay rice stubble.
